How important is a fresh throttle body gasket?

The first time I took my TB off/apart the original paper gasket was destroyed - stuck to both surfaces and needed to be carefully scraped off. So of course I replaced it and bought some spares to keep on hand in the future. Maybe because of that (joking), each time I've taken it apart since then (~3+ times), the gasket comes off cleanly, in one piece. Looks good so I put it back, and have had no problems.

So my advice would be that if it looks OK and is not torn at all, you should be fine. But if you're getting parts ready before doing a job, buy one of these so you're not stuck in case you need it.
